Who's me?

What if you became an entirely different person? Your personality just changed without your say, and you became someone else all together, no memories of who you were before. How would you manage to make it through this obstacle and begin to live life in the way you once had?
This is my story, the true events that have occurred in my lifetime, and how I live with a traumatic brain injury and post-traumatic stress disorder, and I hope that this will raise awareness of the mental problems that rule my life.
